Stop timer in dungeon's if player leaves

[Avorniel]

but you can still make progress without them.

none of us were able to tank,I tried as I was on my summoner but carbuncle couldn't be kept alive as some of the mobs came in grps of 4-5,we had no sleeper so no we couldn't progress,if we had a BLM/WHM as they both can sleep mobs,then yes it may of been doable up to the first boss,but then we still be sitting and waiting for a tank...

first group was summoner (me),Lancer,WHM,Tank whole group split due to many deaths and qqing at first boss
Second group Summoner x2 ,Scholar,Tank ...tank left shortly followed by other summoner we didn't even get started
Third group Summoner (me),Scholar,Bard,Tank ... Tank left at the start while other 2 players were in cut scene

They didn't Disconnect as this leaves the member still in the group for a short period of time (about 5 mins) both times they just up and left group
